LabSat 3 Turntable System by RACELOGIC is an effective and affordable GNSS Navigation Dead Reckoning (DR) Simulator.
If you are selling, testing or developing dead reckoning (DR) products incorporating GPS engines, then you'll find the LabSat 3 Turntable System makes your job easier, quicker and more effective.
Why use a turntable?
The turntable system can use GPS, Galileo, GLONASS or BeiDou satellite constellation data to record live drive data combined with vehicle yaw rate and wheel speed information. The turntable system can work with any GNSS based dead reckoning (DR) system.
All of this data is replayed in perfect alignment so that the turntable will simulate the physical turning required to activate the DR in the navigation system under test. The wheel speed and satellite RF data will activate the navigation system and in combination with video provide a realistic replay of the driven route.
How does it work?
The LabSat then streams the previously recorded file containing satellite navigation signals back to the device under test - faithfully reproducing the navigation signals from all of the satellites which were present during the recording.
Any Satellite Based Augmentation Signals (SBAS) WAAS/EGNOS/QZSS signals present are also reproduced.
At the same time the LabSat software also replays the video, turntable and wheel speed data in sync with the satellite signal recording.
The turntable will turn to simulate the rate of turn (yaw) of the original vehicle turning. This results in a full replay of the actual route taken and will stimulate the dead reckoning (DR) system to activate.
As it is based on a real recording the data will replicate the satellite signal loss experienced in city centres and tunnels and maintain the DR solution until the signals are regained, just like the live drive. This makes the replay repeatable time and again to save you significant testing costs.
The LabSat turntable system can also simulate profiles anywhere in the world.

Why use a video replay?
The Video VBOX system can also create a custom scene in which a range of user defined data can be displayed on the video replay. This includes logos, headers, receiver data and information from the IMU. The picture within picture feature can also record the real time navigation screen data in a test vehicle for comparison, as well as the forward/rear facing camera picture.
